Additionally, the mobile wireless device 202 includes a power supply 216, such as a battery, and an optional vehicle function transmitter 218. The vehicle function transmitter 218 may be adapted to transmit wireless signals that are related to controlling a function of a vehicle.

The communication control module 212 may be adapted to receive communication data from the service provider server 230 via the antenna 204 and the transceiver 206. The communication data may be related to phone calls, emails, text messages, website content, other data directed to the mobile wireless device 202, or any combination thereof. In a particular embodiment, the communication control module 212 determines if the communication data indicates a vehicle function command, where the vehicle function command is related to a particular function of a vehicle. For example, the vehicle function command may be related to unlocking a vehicle door, starting the engine of a vehicle, shutting off the engine of a vehicle, limiting the speed of a vehicle to a threshold speed, controlling another mechanical system or electrical system of a vehicle, or any combination thereof. Additionally, the vehicle function command may include a security code or authentication information related to the security code, where the security code is adapted to activate a requested vehicle function. In an illustrative embodiment, the vehicle function command may be related to a vehicle that is owned, leased, or otherwise associated with a user of the mobile wireless device 202. The mobile wireless device 202 may be associated with a subscription to a remote vehicle function activation service provided via the service provider server 230.

In a particular embodiment, the vehicle function module 214 is adapted to transmit a wireless signal when communication data received at the mobile wireless device 202 indicates a vehicle function command. The wireless signal is adapted to activate the particular function of the vehicle indicated by the vehicle function command. The vehicle function module 214 may send the wireless signal to a vehicle function system coupled to the vehicle. The vehicle function module 214 may be adapted to send wireless signals to activate requested vehicle functions via the transceiver 206 and the antenna 204, via the optional vehicle function transmitter 218, or any combination thereof. In an illustrative, non-limiting embodiment, the vehicle function module 214 may be adapted to transmit a wireless signal to activate a particular vehicle function based on a vehicle function command entered manually at the mobile wireless device 202 by a user of the mobile wireless device 202. For example, the vehicle function command may be entered at the mobile wireless device 202 via a graphical user interface provided by the vehicle function module 214.

In an illustrative embodiment, a remote vehicle function activation service is associated with a plurality of vehicle functions and each vehicle function is related to a distinct wireless signal that is adapted to activate the respective vehicle function. The vehicle function module 214 is adapted to identify the particular function of the vehicle indicated by the vehicle function command and transmit the distinct wireless signal to activate the identified function of the vehicle. For example, the vehicle function module 214 may be adapted to transmit a wireless signal within a different frequency range for each respective vehicle function, to transmit data related to activating a particular vehicle function within the wireless signal, or any combination thereof.

The vehicle function module 214 may also be adapted to transmit distinct wireless signals based on the manufacturer of the vehicle. For example, the vehicle function module 214 may be adapted to identify a manufacturer of a vehicle and determine a set of wireless signals accepted by a vehicle control system of a vehicle based on the manufacturer of the vehicle. The vehicle function module 214 may be adapted to transmit a first set of signals to activate functions of a first vehicle manufactured by a first vehicle manufacturer and to transmit a second set of signals to activate functions of a second vehicle manufactured by a second vehicle manufacturer. In an illustrative, non-limiting embodiment, a first set of wireless signals accepted by a vehicle manufactured by a first vehicle manufacturer may be transmitted on a different range of frequencies than a second set of wireless signals accepted by a vehicle manufactured by a second vehicle manufacturer. The vehicle function module 214 may be adapted to identify the manufacturer of the vehicle based on a vehicle function command received from the service provider server 230, where the vehicle function command indicates the vehicle manufacturer.

Further, the vehicle function module 214 may be adapted to transmit a security code within the wireless signal. The security code may be required by a vehicle function system before activating a particular vehicle function. In one example, the security code may be unique to a particular vehicle. In another example, the security code may be related to security data transmitted from a remote keyless entry device of a vehicle to a corresponding vehicle function system. To illustrate, a remote keyless entry device associated with a vehicle and a corresponding vehicle function system may each include a pseudo-random number generator that generates security data, such as a 40-bit code. The pseudo-random number generator of the remote keyless entry device and the pseudo-random number generator of the vehicle function system may both use the same seed value and the same algorithms to generate the security data. The algorithm utilized by the pseudo-random number generators may be a hopping code algorithm, a rolling code algorithm, a blum blum shub algorithm, an inverse congruential generator, a lagged Fibonacci generator, a linear congruential generator, a linear feedback shift register, a multiply with carry algorithm, or a Mersenne twister algorithm. When the security data received from the remote keyless entry device at the vehicle function system matches the expected security data, the vehicle function system activates a requested vehicle function. Each subsequent time that security data is transmitted from the remote keyless entry device, the transmitted security data is used by the remote keyless entry device pseudo-random number generator and the vehicle function system pseudo-random number generator to generate the next valid security data. In this way, the remote keyless entry device and the vehicle function system are synchronized, such that the remote keyless entry device transmits security data that the vehicle function system expects to receive. In some embodiments, the vehicle function system may generate a range of successive valid security data from security data previously received from the remote keyless entry device to account for activations of the remote keyless entry device that may not be received by the vehicle function system, such as activations of the remote keyless entry device that occur outside of a communication range with the vehicle function system.

The security code may be included in a vehicle function command received from the service provider server 230, the security code may be periodically received from the service provider server 230, or any combination thereof. Alternatively, the vehicle function command may include authentication information related to the security code. For example, the authentication information may be associated with a pointer to the security code, where the security code is stored at the mobile wireless device 202. In another example, the authentication information may include a seed value that can be used to generate the security code, a hash value of the security code, or any other type of information that can be used by the mobile wireless device 202 to generate the security code.

Further, the vehicle function module 214 may be adapted to determine that a requested vehicle function has not been activated after a wireless signal has been transmitted to a vehicle function system and the vehicle function module 214 may be adapted to send a request to the service provider server 230 to receive information associated with an updated security code that is acceptable to the vehicle function system. The vehicle function module 214 may also include a pseudo-random number generator that is seeded with the same initial value as a remote keyless entry device of a vehicle. The pseudo-random number generator of the vehicle function module 214 may also include the same pseudo-random number generating algorithm as a remote keyless entry device of a vehicle. The vehicle function module 214 may be adapted to invoke the pseudo-random number generator to generate a security code that is to be transmitted to a vehicle function system. The pseudo-random number generator may utilize authentication information received from the service provider server 230 to generate the security code. Additionally, the vehicle function module 214 may be adapted to verify that the pseudo-random number generator is using current security data associated with a remote keyless entry device of a vehicle to generate the security code by sending a request to the service provider server 230 for the current security data that is acceptable to a vehicle function system coupled to a particular vehicle.

The vehicle function module 214 may store a vehicle function signal table that includes a list of the vehicle functions that may be activated via the mobile wireless device 202 and the corresponding signals may be used to activate each respective vehicle function. The vehicle function signal table may be downloaded from the service provider server 230 when the mobile wireless device 202 is in a remote vehicle function activation service configuration mode and may be updated as new vehicle functions are added to the remote vehicle function activation service, as the signals used to activate the vehicle functions change, or any combination thereof. For example, if a remote vehicle function activation service adds a feature to control a climate control system of a particular vehicle, the vehicle function signal table may be updated to include one or more wireless signals to control the climate control system of the vehicle. Additionally, a vehicle function signal table may be updated when the security code associated with a particular vehicle function system changes.

In some embodiments, the vehicle function module 214 may be adapted to transmit wireless signals to activate particular vehicle functions in response to receiving a vehicle function command from the service provider server 230 via the transceiver 206 and the antenna 204. In other embodiments, the vehicle function module 214 may be adapted to transmit the wireless signals to activate different vehicle functions via the optional vehicle function transmitter 218. The transceiver 206 may be adapted to communicate via a different range of frequencies than the vehicle function transmitter 218. To illustrate, the vehicle function module 214 may send wireless signals within frequency bands used by mobile wireless devices, such as the 700 MHz, 800 MHz, 850 MHz, or 1900 MHz frequency bands, via the transceiver 206 and the antenna 204, to control specified functions of the vehicle. In another illustration, the vehicle function module 214 may send a wireless signal on a same frequency band as the frequency band associated with a remote keyless entry device associated with the vehicle, such as a 300 MHz or 400 MHz frequency band, via the optional vehicle function transmitter 218 to control certain functions of the vehicle. For example, a wireless signal to control the locks of a vehicle may be sent via the vehicle function transmitter 218, while a wireless signal to shut off the engines of a vehicle may be transmitted via the transceiver 206 and the antenna 204. The frequency of a wireless signal adapted to activate a vehicle function system may be retrieved from a vehicle function signal table stored at the vehicle function module 214 or the vehicle function command received from the service provider server 230 may indicate the frequency. In an illustrative, non-limiting embodiment, the optional vehicle function transmitter 218 may be a one-way transmitter.

In a particular embodiment, the service provider server 230 includes one or more interfaces 232 adapted to communicate via the one or more communication networks 220 and processing logic 234, such as one or more independent or redundant processors, coupled to the interfaces 232.

Further, the account module 238 is adapted to activate the remote vehicle function activation service with respect to the mobile wireless device 202 after receiving the enrollment request and to establish an account for the requesting subscriber. The account module 238 may be adapted to place the mobile wireless device 202 into a configuration mode after the remote vehicle function activation service has been established to activate hardware, such as the vehicle function transmitter 218, to download software, to provide a vehicle function signal table, to provide a security code or authentication information related to security codes that are adapted to activate particular vehicle functions, or any combination thereof, to enable the mobile wireless device 202 to provide the remote vehicle function activation service. In addition, the account module 238 may charge a fee to an account associated with the remote vehicle function activation service after receiving a vehicle function request related to activating a particular function of a vehicle, after sending a vehicle function command to activate a requested function of a vehicle, or any combination thereof.

In a particular embodiment, the communication control module 240 is adapted to receive communication data from the remote device 250, the mobile wireless device 202, or any combination thereof. The communication data may be related to phone calls, emails, text messages, Internet Protocol data, or any combination thereof. For example, when the service provider server 230 is associated with a wireless communication service provider, the service provider server 230 may be operable to route calls and data to and from the mobile wireless device 202.

Additionally, the communication control module 240 is adapted to determine if the communication data indicates a vehicle function request, where the vehicle function request indicates a request to activate a particular function of a vehicle. The service provider server 230 may receive communication data from the mobile wireless device 202, the remote device 250, or any combination thereof, indicating a vehicle function request. In an illustrative embodiment, the service provider server 230 receives the vehicle function request from the remote device 250 via a website provided by the service provider server 230. In another illustrative embodiment, the service provider server 230 may receives the vehicle function request from the remote device 250 via a phone call. For example, a user of the remote device 250 may call a 1-800 number or another specified phone number associated with a remote vehicle function activation service. The communication control module 240 may invoke the vehicle function module 242 when the communication data indicates a vehicle function request

After receiving a vehicle function request, the vehicle function module 242 is adapted to provide one or more interactive voice response (IVR) menus when the vehicle function request is received via a phone call. Additionally, the vehicle function module 242 is adapted to provide one or more graphical user interfaces when the vehicle function request is received via a website. The IVR menus and graphical user interfaces provided by the vehicle function module 242 may be adapted to guide a user through a series of steps related to making a vehicle function request. For example, the vehicle function request IVR menus and graphical user interfaces may be related to a login step, where an identification code, such as an account number, subscriber password, or any combination thereof, are entered. The vehicle function request IVR menus and graphical user interfaces may also be related to a vehicle function selection step where a vehicle function that a subscriber desires to activate is chosen from a list of selectable options.

After the vehicle function module 242 receives an identification code associated with a vehicle function request, the vehicle function module 242 is also adapted to determine if the identification code is associated with a valid subscription to a remote vehicle function activation service. In an illustrative embodiment, the vehicle function module 242 compares an identification code associated with a vehicle function request to a list of identification codes related to valid remote vehicle function activation service subscriptions. The vehicle function module 242 then determines if the received identification code matches an identification code associated with a valid remote vehicle function activation service subscription.

In a particular embodiment, the vehicle function module 242 sends a vehicle function command to the mobile wireless device 202 when the identification code is associated with a valid remote vehicle function activation service subscription related to the mobile wireless device 202. The vehicle function command is adapted to cause the mobile wireless device 202 to transmit a wireless signal to activate the particular function of the vehicle. The vehicle function command may include a security code or authentication information related to the security code that a vehicle function system may expect to receive before activating a requested vehicle function. The vehicle function module 242 may be adapted to request the security code, or authentication information related to the security code, from a vehicle function system of a particular vehicle periodically, in response to receiving a vehicle function request, or any combination thereof. Alternatively, a vehicle function system of a particular vehicle associated with a remote vehicle function activation service subscription may be adapted to periodically send updated security data to the service provider server 230. Further the vehicle function module 242 may be adapted to send periodic updates associated with a security code to the mobile wireless device 202.

The vehicle function module 242 may also send a vehicle function command to the mobile wireless device 202 in response to receiving a vehicle function request indicating an emergency identification code. The emergency identification code may be received from an emergency response entity or a law enforcement entity to activate a particular function of a vehicle in an emergency situation without receiving a subscriber identification code. For example, the remote device 250 may be associated with a law enforcement entity and the service provider server 230 may receive a vehicle function request from the remote device 250 to reduce the speed of a vehicle that has been reported stolen. In another example, the remote device 250 may be associated with an emergency response entity and the service provider server 230 may receive a vehicle function request from the remote device 250 to open the doors of a vehicle after an accident has occurred involving the vehicle.

In an illustrative embodiment, each vehicle function is one of a plurality of vehicle functions associated with the remote vehicle function activation service and the vehicle function module 242 is adapted to send a vehicle function command to the mobile wireless device 202 based on the respective vehicle function requested. For example, the vehicle function module 242 may be adapted to send a first vehicle function command to the mobile wireless device 202 when the vehicle function request is related to unlocking a door of a vehicle and to send a second vehicle function command to the mobile wireless device 202 when the vehicle function request is related to turning on the engine of a vehicle.

Additionally, the vehicle function commands sent by the vehicle function module 242 to the mobile wireless device 202 may be based on the manufacturer of a vehicle. To illustrate, the vehicle function module 242 may be adapted to identify the manufacturer of a vehicle associated with a received vehicle function request and send a first set of vehicle function commands to the mobile wireless device 202 when functions of a first vehicle manufactured by a first vehicle manufacturer are to be activated and to send a second set of vehicle function commands to the mobile wireless device 202 when functions of a second vehicle manufactured by a second vehicle manufacturer are to be activated.

In embodiments where a remote vehicle function activation service subscription is associated with a plurality of vehicles, the vehicle function module 242 may be adapted to identify the particular vehicle associated with a vehicle function request. The vehicle function command sent to the mobile wireless device 202 by the service provider server 230 may be related to the identified vehicle.
